History of Elden | The Cars

Mk 7 – Sturgess PRH 7

Formula F100 Sports Racing Car | 1969 | 3 Cars Produced

The Elden / Sturgess (sometimes erroneously spelled Sturdgess) PRH 7 is a Formula F100 Sports Car originally designed for the Tarmac F100 championship using a Ford Kent 1300cc engine. The bodywork was designed and made by Tony Hilder, the bodywork designer for McLaren.

The cars struggled with overheating: the inlet to the front mounted radiator was underneath the nose with the outlet on top. Factory produced bodywork subsequently had a notch cut in the front of the nose to aid with improved cooling. The issue would later be solved by using a lip to direct the flow, reducing pressure on the radiator outlet and so allowing better airflow through the radiator.

Four chassis were fabricated. At the same time, Elden started on mass production of the Mk 8 Formula Ford and needed factory space, so three of the chassis were sold to Clarke Sturgess who finished their construction. The fourth car was never finished and so put into storage and was eventually modified into the Mk 11 Sports Racing Car.

One car was purchased by Mark Cole from Hot Car Magazine and the other two originally driven by Clarke and Chris Lee.

All three finished cars are still racing today.
